-------------------------------------
Summary: hand btree rebalance case when it can't get table level
lock.
Key: DERBY-6873
URL: https://issues.apache.org/jira/browse/DERBY-6873
Project: Derby
Issue Type: Improvement
Reporter: Mike Matrigali
current implementation of btree requires table level lock on index to
rebalance. This can result in inefficient tree structure if lock can not
be obtained and if post commit retry also fails. Similar to other problems
if post commit retry does not succeed.
May also leave unreclaimed space that could be reclaimed.
Work around is to run compress on the table in offline mode.
